Paper Abstract

We propose a novel spectroscopy by combining Kramers-Kronig analysis and OCT. It can realize the non-contact measurement to resolve the spectra of the direct-contacted dielectric layers as color tomography, which we call spatially-resolved spectroscopy. In this paper, we simulate the proposed method that can be applied to the measurement of the amplitude reflectance spectrum using a glass plate on normal incident condition. As a demonstration, the glass sample was experimentally observed by TD-OCT and applied to K-K analysis. The result indicated that the proposed method is achievable to the spatially resolved spectroscopy for direct-contacted dielectric multilayers.
